Significant avalanche danger prevails in southern Jämtland mountains and western Härjedalen, according to Lavinprognoser.se. Dangerous conditions are caused by wind slabs that can trigger avalanches under load. The warnings are in effect until Tuesday at 18:00.
According to the Swedish Environmental Protection Agency's site Lavinprognoser, level 3 significant avalanche danger is in effect in the southern Jämtland mountains and western Härjedalen. These areas, home to several winter sports resorts, have dangerous conditions due to wind slabs formed on the lee sides of the mountains. The site states that these slabs can cause avalanches when loaded by a skier, snowmobile, or falling cornice.
The advice is to avoid slopes steeper than 30 degrees with smooth wind crust and the terrain below such slopes until the snow has stabilized. “Sometimes it's just surface snow that slides, but the wind crust can also crack much deeper, which can lead to large avalanches,” the site notes.
The warnings are issued until Tuesday at 18:00. Significant avalanche danger corresponds to a 3 on the five-grade scale, where it is likely that people will trigger avalanches and spontaneous ones are possible.
In nearby areas like the southern Lapland mountains and western Vindelfjällen, the danger is assessed as moderate, level 2. The situation in Kebnekaise mountains as well as Abisko and Riksgränsen has not been assessed. The avalanche scale describes level 1 as low danger with generally safe conditions, up to level 5 with certain occurrence of avalanches.
The news was published on December 29, 2025, with SVT's report shortly after 20:00 and Aftonbladet's at 19:46.
